Patent CA-2044616-A1 (CA)
Title: Dna sequencing
Inventor: TSIEN ROGER Y
IPC: C07H21/00
Filed: 1990-10-26
Abstract: The present invention relates to an instrument and a method to determine the nucleotide sequence in a DNA molecule without the use of a gel electrophoresis step. The method employs an unknown primed single stranded DNA sequence which is immobilized or entrapped within a chamber with a polymerase so that the sequentially formed cDNA can be monitored at each addition of a blocked nucleotide by measurement of the presence of an innocuous marker on specified deoxyribonucleotides. The invention also relates to a method of determining the unknown DNA nucleotide sequence using blocked deoxynucleotides. The blocked dNTP has an innocuous marker so that its identity can be easily determined. The present instrument and method provide a rapid accurate determination of a DNA  nucleotide sequence without the use of gel electrophoresis.
Patent CA-2046413-A1 (CA)
Inventor: NARAHASHI SHOICHI
IPC: H03F1/32
Filed: 1991-07-05
Abstract: ABSTRACT OF THE DISCLOSURE     In a feed-forward amplifier which has an error detection circuit for detecting a nonlinear distortion component of a main amplifier and an error rejection circuit for amplifying the detected distortion component by an auxiliary amplifier and injecting it into the main amplifier to thereby cancel an error component, a first pilot signal is injected into a signal input path and a second pilot signal is injected into a signal amplification path of the error detection circuit.  A first variable attenuator and a first variable phase shifter of the error detection circuit are adjusted by a control circuit so that the level of the first pilot signal component on an error injection path of the error rejection circuit decreases to minimum.  A second variable attenuator and a second variable phase shifter of the error rejection circuit are adjusted by the control circuit so that the level of the second pilot signal component on a signal output path decreases to a minimum.  The first pilot signal component which appears on the signal output path is rejected by inserting therein a filter or cancelled by supplying the error injection path or signal output path with the first pilot signal after adjusting its amplitude and phase. Alternatively, the frequency of the first pilot signal to be injected into the signal input path is spread to thereby lower the level of the first pilot signal per unit spectrum which appears on the signal output path.

Patent CA-2052735-A1 (CA)
Title: Water fountain trough for offset press
Inventor: BOSSE GERARD
IPC: B41F31/06
Filed: 1990-10-03
Abstract: ABSTRACT         There is disclosed a unique and improved fountain dampening solution basin for use with an offset printing press water roller.  Problems with the transfer of dampening solution to a plate cylinder are encountered when the offset press heats up on long press runs.  As more water is transferred to the plate cylinder, it mixes more with the ink and an emulsion produces a mist about the press.  This produces ink droplets which collect in the fountain solution basin.  Ink droplets in the fountain solution basin are picked up by the water roller and block the brush roller thereby decreasing the effectiveness of the dampening solution on the plate cylinder, causing smudging of the print.  By placing a vertically oriented baffle in the basin, extending from the floor thereof, a predetermined level of water is maintained on the water roller side of the basin.  The fountain dampening solution overflows to the opposite side of the baffle in a waterfall action.  It is then removed from the basin through a drain.  This flow over the baffle tends to draw the ink droplets to the baffle and over since they have a lower specific gravity than water.  This eliminates the buildup of ink in the basin so that a constant even supply of water to the brush and plate roller can be maintained.
